Lamination ceramic condenser, dielectric ceramics, production manner of lamination ceramic electronic parts and lamination ceramic condenser

摘要

Ten minutes low temperature calcination is possible, the dielectric ceramics, and the lamination ceramic electronic parts which use that (lamination ceramic condenser etc whose at the same time resistivity at high temperature is high) it offers. Lamination ceramic condenser 1, the layered product outside was formed on external surface of 2 which has the electrode 4 inside the multiple which is formed the multiple dielectric ceramic formations according to the surface between 3 which are laminated and dielectric ceramic formation 3 and layered product 2 electrode to include with 8 and 9, composition of layered product 2, the perovskite die chemical compound which includes Ba and Ti (however, as for the portion of Ba to be good being displacement with Ca, the portion of Ti is good being displacement with Zr) to make the main component, furthermore, as for M (M Cu, Zn, Li and K, andAt least kind among Na) with it includes with Bi, when designating the total content of Ti and Zr as 100 mol sections, total content of M and Bi is 3 mol sections or more, it features that crystal grain size of dielectric ceramic formation is below 150nm above 30nm.
